Its no longer visible to the user. You can go to the folder by using the Go to Folder using username/library using the go to folder option to the right of the Finder labeled Go, then Go to Folder. Then you can see the contents of the user library folder.

  • Macbook Pro can't find Wifi after closing

    I moved house and got a new wifi provider. My Macbook Pro can't find it sometimes after I close my Macbook which forces me to restart for it to join the network automatically. SOMETIMES I get a popup window with networks that it picks up and SOMETIMES my network is listed and I can select that, but not all the time. Why cant my Macbook find my network sometimes? It can find everybody elses except mine!

  • Macbook Pro can't find my home wifi

    I just got my battery replaced.. All my data disappeared. The worst thing is, I can't find my home wifi network but my neighbour wifi network is available. Pls help me fix this.
    Mine is a MBP 2011.
    Your help is much appreciated!

    Hello, Sallyelainelee!
    You may want to check the settings on your Router to make sure there isn't something in its configuration that's preventing the MacBook Pro from seeing it. If the MacBook Pro can connect to other WiFi networks OK, I would imagine that this would be the case.

  • MacBook Pro can't find my NAS (My Book World)

    I can't get my MacBook Pro to find my WD NAS (My Book World) on my home network. I have other devices that can find the NAS - Windows PCs and even an iTouch - so it is just my MacBook that can't find it.
    Anybody got any suggestions?

    Same problem here. Shows up on my PC latop but my Mac Mini can't find the WD MBW. On other forums Itunes updates is mentioned as a cause???
    Anyone have a suggestion?
    I have 1,5 TB movies and music so this is pretty frustrating

  • Macbook PRO can't find ANY Wifi network - only at home

    Hi, i have a very strange problem with my *Macbook Pro*. I have 3 apple computers at home and one pc. On all machines Wifi works fine, except my new alu Macbook Pro. Important note is, when im with my macbook on other place, office, caffe, *Wifi works fine. But when im at home, this macbook simply can't find ANY network, it's blind.* Interesting thing is, all other computers are several years old and WiFi works fine on them. My friend also bought a brand new macbook pro, and this machine also couldn't fine any network at my home, or in other case when it found networks, it couldn't connect and recieve error message "Connection timed out". I noticed there is new Wifi network in our range, is it possible that this network can cause "blindness" on new macbooks?

    *I have to say, I'm really glad you are trying to help guys.*
    Well, router is almost on default settings, SSID is brodcasted and i'm not filtering MAC adresses. I tried changed channels, diffrent types of security or no security, no luck.
    Guys, maybe i wrote it wrong, but this MacBook can't see ANY network. Around me there are 4-6 other networks which I'm able to see from other machines. So *problem is, this Macbook can't seen ANY network - not just mine.* BUT when i'm with this Macbook in office for example, or any other location, Wifi works....
    And one more important thing, this happened suddenly. I was able few months ago to find any WiFi around me with this Macbook. No changes to router, no changes to mac. Problem is somwhere in the middle...try to focus on this: why i'm not able to see any of those cca 6 networks around me. I really think it has to do something with distorted signal and Wifi card used in new macbooks. It's really sick, because all other machines works perfectly (MB 07, MBP 06, PC, iPhone 3g)
    I found a log on the router, and it's happening all the time:

    what should i do next. any one got same problem with me?
    please advise
    Thanks

    it's the cable that goes from your hard drive to your logicboard....those cables have a high failure rate without warning....
    to confirm that it's your cable and not your drive, install your drive in an external usb enclosure and if you can boot your macbook when your drive is connected via usb, then it's your sata cable...

  • MacBook Pro Can't find home wireless network

    I've been having some issues getting my macbook pro, running OS 10.7.5, to find my home wireless network. The network doesn't show up when it searches automatically, and when I type the network name in to find it manually, it says no network found. The computer connects to all other networks and finds then with no issues, and other MacBooks are able to find my home network and connect to it again with no issues.
    The computer used to be able to find the network, and then it just stopped working. I have tried all the standard fixes, resetting the router, computer, PRAM, forgetting the network, deleting the key from keychain, but nothing seems to work. I tried googling the issue, but wasn't able to find a problem similar to the one I have.
    Any advice would be greatly appreciated.
    Thanks

    Still having problems with this.
    I have upgraded to Mavericks, hoping that the problem would be fixed, but it hasn't. I still get all networks completely disappearing - even if I search for them they are not found.
    But I reboot the computer and it works! But when I am in OS or Bootcamp mode and put the Mac to sleep, it does not see the networks again! I have to reboot the computer for it to work.
    I have even got a new router which can receive the b,g and n signals etc. as I was told by a Mac techie here that Macs 'look' for the n signal but can also work with the b and g signals and THAT maybe my old router only transmits b and g or something like that .
    This, to me, sounds like a Mac software problem. I had a similar problem on a previous Mac on my "old router" and a totally different router in a different country's telephone system.
    I now have the same problem with a new MBP on a new router!

  • Macbook Pro can't find properly working Airport Express network

    I have an Airport Express that's set up and working properly, and my Mac Mini and my iPhone both find the airport network, but not my MacBook Pro. The MacBook pro is even closer to the Express than the Mini is, and it finds many available airport networks (from the neighbors), but not my own network that the other units find without a problem - my own network just isn't listed among the others on the MacBook Pro, and Airport Utility on the MBP can't find the Express either. I've obviously tried restarting everything, as well as resetting the Express and setting it up again (which works just fine from the other two units), and I've tried creating a new user account on the MBP and check from there, but no go. The MBP runs the latest version of Snow Leopard and works just fine with other Airport Networks (at work, or one of the neighbors networks even), so it shouldn't be faulty hardware. At some point it's time for a Lion update for the MBP and then we'll see if it's some weird system software error that gets resolved in the process. But until that happens … what else could I try?
    I'm thinking maybe this is some 802.11 b/g/n malfunction? The Express is an old g, the iPhone is g only, and the Mini is an old g as well, but the MacBook Pro is newer and supports n … but it should of course still be able to switch down to g and find the **** network (or the Express when running Airport Utility).
    Anyone?

    Well, I can't delete the wireless connection since it doesn't really exist (on the MacBook Pro). Had the Express in my office, but brought it home, and reset it there and created a new network using the Mac Mini, so the MacBook Pro had never been connected to that newly created airport network. But I did delete a lot of old saved connections, some of which were from when the Express was used in my office. This was however, before I read your reply here, so I didn't also erase the passwords from the keychain, however. But still no go; the MacBook just wouldn't list the new network among the available ones, or list the Express in the Airport Utility.
    But then … last night, for no apparent reason whatsoever, suddenly everything just works.
    In trying to wrap my head around this, and learning from it. Is it even possible for an old network used on an Airport device to interfere with a new network created by the same device? What I mean is, does the computer identify the airport by some sort of serial number or something, regardless of the network created by the airport? So that when a computer should be looking for a new and current network on an airport device it instead looks for an old network it has previously been connected to on that same airport device? Assuming the old network should still exist on that same device, and therefore skipping to look for a new network on the same device? I mean that would suck, but if that's the case then at least I'd know to always erase all traces of any old connections for a specific device in a case like this. ;-)
    Thanks for your input!
    Cheers!

  • My MacBook Pro can not find my internal hard drive.

    My computer does come on. And I have a MacBook Air 2009. Just some history, my computer froze on me one day. So I restart it and a screen with a folder and question mark showed up. So I called apple and got some trouble shooting done. Nothing worked. So they ended up sending me another installer disk. And that did not work. Could not find my internal hard drive. So I took it to a apple store and the guy who looked at it told me that it was water damaged and would cost $700 to fix. So I pushed it to the side for year and decided to take a further look into it recently. And found some information where people had the same issue and was advices their hard drive could be dead. So I'm thinking about getting a 2nd opinion and taking it some where else. I'm just wondering could I really just replace my hard drive and be fine with my computer? If its really water damaged wouldn't it not work? Does replacing the hard drive cost a lot to do?

    Its extremely unlikely your HD is water damaged, everything on your internals in your macbook Pro would FRY long before water seeped its way into your HD,....the HD circuitry on the outside of the HD however is another story.
    If your computer IS in fact water damaged, then yes, replacing the hard drive wouldnt fix anything.
    Replacing the HD yourself , IF your HD is dead and at fault, can be done by yourself easily and cost around $65.
    In any regard, on a 2009 computer....., 700$ could buy you a nice MUCH NEWER and faster like new refurbished MAC,........as such it would be best not to consider such an option.

  • Macbook pro can´t find/connect to my hotspot

    Dear experts!
    I recently moved to a new place and got myself a T-Mobile HomeNet Router. Everything works fine (WiFi and Ethernet) with all devices (iPhone, iPad, iMac, Linux-machine...) EXCEPT my MacBook Pro (specs below in the product section) :-(
    Ever since I moved the Macbook can´t find or connect to my home hotspot. Settings on the router are as follows:
    - 802.1 b/g (it IS capable of b/g/n but I found a thread somewhere pointing out that this could be an issue)
    - channel 13 (deactived auto-channel because my neighbours had overlapping channel settings...this was the only one that worked)
    - rate auto
    - frequency 2.4 GHz
    - 30% signal strength (same reason as above)
    - QoS activated
    - SSID hidden (tried broadcasting it, made no difference)
    - WPA2-PSK
    - AES (TKIP and TKIP+AES available as well...but neither made any difference)
    I can connect via ethernet, however that´s not the intended purpose of neither my notebook nor the router :-/ Someone suggested it might be an encryption issue but even without  ANY encryption the hotspot won´t show up in the list. Password contains special characters but even my old iMac doesn´t seem to have problems with it. I tried connecting manually via "other network" without success. Also via Controlpanel -> Network -> Assist me ...
    I´m sitting right next to my router so the signal strength can´t be the cause either (besides all other devices work just fine anywhere in my appartement). Restarted all devices, each one is up to date. Last thing I tried was making the changes in Firefox cause someone suggested it might be a bug in the router software, still no success.....I´m out of ideas.
    Posted this in another Mac forum already but no one could help me :-( You guys are my last hope ... does anyone know this issue and how to solve it??
    any ideas would be greatly appreciated!
    many thanks in advance

    My MacBook Pro (OSX 10.6.8) can not find the FireWire port. Until now there hasn't been any problems using the FireWire, but now it just deny any knowledge of it, so to speak.
    The audio device lights up when I connect it to the MBP (yes, I did connect it when in off-mode), so it seems to work in a way.

  • Macbook Pro can't find my Mac OS partition

    Hello,
    My Macbook Pro recently received a software update. When I restarted it, it could not boot from my Mac OS partition. I unmounted and remounted the OS section...same issue.
    When I tried to reinstall Mac OS to the partition, it could find the Mac OS partition, but the installation would not complete due to some sort of error. I repaired the partition, and got a message that everything looked OK, but trying to reinstall the OS again resulted in another failed message.
    It will still not find the Mac OS partition as a bootable drive, but my Windows partition is fine.. I'm so confused as to what the issue is here, so hopefully someone can help me.
    Thank you!

    Hold the option key down while booting, see if OS X appears and select it to boot from, then reset the StartupDisk in System Preferences again.
    If that doesn't work, I suspect a hosed GUID partiton table, backup what you can out of Windows to a external drive and disconnect.
    Next read this to recover data out of your OS X parittion if you don't have a backup
    Create a data recovery, undelete boot drive
    Hold c or option boot off the installer disk and use Disk Utility to zero erase the entire drive and reinstall as follows
